CHAPTER 4: History, Physical Examination and the Preoperative Evaluation Flashcards
Indicative of temporal bone fracture
Battle sign (ecchymosis overlying the mastoid)
To straighten the canal and allow atraumatic insertion of the otoscopic speculum
Gently grasp the pinna and elevate it superiorly and posteriorly
TRUE or FALSE
The lateral process of the malleus is readily seen in the superior TM and will be quite prominent in retracted membrane
TRUE
TM lacks the radial and circular fibers
Pars flaccida
Most common location for retraction pockets, debris, and cholesteatoma
Pars flaccida
TRUE or FALSE
The normal TM should be pearly gray and translucent
TRUE
A thickened, erythematous membrane, occasionally with bullae
Myringitis
A thin atelectatic membrane draped closely over the underlying middle ear structure
Adhesive otitis media
Prominent radial blood vessels
Chronic middle ear effusion
Often appear as amber fluid, sometimes with air-fluid levels or air bubbles
Serous effusions
Appear dull gray to white in color, with loss of the typically visualized middle ear landmarks, and the TM will often be retracted
Mucoid effusions
Mass blanches with pneumatic otoscopy
Brown sign
Tuning fork tests is done to distinguish between a sensorineural and conductive hearing loss with a
512-Hz fork
Performed by placing the vibrating 512-Hz tuning fork in the center of the patient’s forehead, at the bridge of the nose, or on the central incisors with the patient’s teeth tightly clenched
Weber test
The 512-Hz tuning fork is placed firmly on the mastoid process, and the patients are instructed to tell the examiner when they are no longer able to hear the sound. The fork is then quickly transferred in front of the ear canal, and patients are asked if they can hear the sound
Rinne test
NPCA most commonly presents in the
Fossa of Rosenmuller
Boundaries of the oral cavity
- Skin-vermillion junction of the lips
- Hard palate
- Anterior 2/3 of the tongue
- Buccal membranes
- Upper and lower alveolar ridge
- Retromolar trigone
- Floor of the mouth
Parotid duct or Stenson duct opens near the
2nd upper molar
Small yellow spots in the buccal mucosa are sebaceous glands
Fordyce spots
Oropharynx area
- Posterior 3rd of the tongue
- Anterior and posterior tonsillar pillars
- Soft palate
- Lateral and posterior pharyngeal wall
- Vallecula
Tonsil size/scale
Brodsky scale
Indicates the tonsils are entirely within the tonsillar fossa
0
Indicates the tonsils are located just outside the fossa and occupy <25% of the total width of the oropharynx
1+
Tonsils occupy 26%-50%
2+
Tonsils are 51%-75% of the oropharyngeal width
3+
Tonsils occupy >75% of the oropharyngeal width
4+
Larynx is subdivide into
- Supraglottis
- Glottis
- Subglottis
Area of supraglottis
- Epiglottis
- Aryepiglottic folds
- False vocal cords
- Ventricles
Area of glottis
- Inferior floor of the ventricle
- True vocal folds
- Arytenoids
Area of subglottis
Begin 5-10mm below the free edge of the true vocal fold And to extend to the inferior margin of the cricoid cartilage
Extends from the superior edge of the hyoid bone to the inferior aspect of the cricoid cartilage
Hypopharynx
Subsites of hypopharynx
- Piriform sinuses
- Posterior hypopharyngeal wall
- Postcricoid area
Correct positioning in indirect laryngoscopy
- Patient’s legs should be uncrossed and placed firmly on the footrest
- The back should be straight with the hips planted firmly against the chair
- While leaning slightly forward from the waist, the patient should place the chin slightly upward in a sniffing position
- The patient’s tongue is pulled forward by the examiner
- The examiner’s middle finger is extended to retract the patient’s upper lip superiorly, and a dental mirror is warmed to prevent fogging and is placed in the oropharynx to elevate the uvula and soft palate to view the larynx
Divides the neck into a posterior triangle and anterior triangle
SCM
Posterior triangle comprises of
Supraclavicular and occipital triangles
Anterior triangle comprises of
- Submandibular
- Carotid
- Muscular
Defined by the body of the mandible, the anterior belly of the contralateral digastric muscle, and the stylohyoid muscle
Level I
Contains submental nodes
Level IA
Consists of the submandibular nodes
Level IB
Levels IA and IB are separated by the
Ipisilateral anterior belly of the digastric muscle
Upper third of the jugulodigastric chain is known as
Level II
Middle jugulodigastric chain
Level III
Lower jugulodigastric chain
Level IV
Located medial to the plane defined by the spinal accessory nerve
Sublevel IIA
Lateral to the spinal accessory nerve
Sublevel IIB
Extends from the inferior border of the hyoid bone to the inferior border of the cricoid catilage
